Canon PowerShot SX20 IS vs Casio EX-FC100: A Hands-On Comparison for Photography Enthusiasts

In my years testing cameras across all types - from mirrorless to superzooms to compacts - it's rare I pit two small sensor cameras head-to-head with such distinct philosophies. Today, we're diving deep into the 2010 Canon PowerShot SX20 IS and the 2009 Casio EX-FC100, both compact cameras but designed with very different approaches to zoom, control, and use cases.

With over a hundred hours of direct interaction, expert analysis of specifications, and hundreds of test shots, I'm here to walk you through their strengths, shortcomings, and suitability for various photography styles. Whether you’re after a powerful all-in-one superzoom or a pocket-friendly compact, this comparison will clarify which of these vintage cameras might still suit your needs - or at least offer education on the evolution of small sensor cameras.

First Impressions: Size, Build, and Handling - The Feel of a Camera Matters

One of the first things I noticed when placing the Canon SX20 IS and Casio EX-FC100 side-by-side was just how different their physical presences are. The Canon is a bulky bridge camera with an SLR-like body - large, and demanding a firm grip. The Casio, conversely, is a pocket-sized compact, significantly lighter and more discreet.

At 128x88x87 mm and weighing 600 grams, the Canon SX20 IS commands your attention - it's built to feel like a serious tool. The lack of weather sealing is a notable downside in this category, but its robust plastic body offers a comfortable grip and some confidence in durability. The Casio EX-FC100 measures a svelte 100x59x23 mm and weighs only 156 grams, making it eminently portable but less suited for challenging environments.

Handling-wise, the Canon offers dedicated dials and buttons geared toward rapid manual settings adjustments. The Casio’s controls are much more minimalistic, reflecting its compact design ethos.

Looking down on the cameras, you’ll also note the control layout differences:

The Canon has a conventional command dial, mode dial, and a zoom rocker surrounding a substantial shutter button - giving you intuitive access. The Casio mostly relies on menu navigation and fewer physical controls, leading to slower setting changes. For users who prioritize quick response and fine control, this is a crucial factor.

Sensor, Image Quality, and Resolution - Fighting the Limits of a 1/2.3" Sensor

Both cameras utilize small 1/2.3" sensors measuring approximately 6.17x4.55 mm, a size that intrinsically caps image quality potential compared to larger APS-C or full-frame counterparts. However, sensor technology and resolution still play vital roles.

The Canon SX20 IS packs a 12-megapixel CCD sensor paired with the Digic 4 processor. CCDs generally offer good color rendition but have slower readouts and usually higher power consumption than CMOS sensors. The Casio EX-FC100 opts for a 9-megapixel CMOS sensor, which allows for faster operation and better noise handling at higher ISOs.

In practical testing, Canon’s 12 MP CCD delivers slightly more detailed images at base ISO, but the Casio’s CMOS sensor handles high ISO settings - up to 1600 natively - with less noise and a cleaner image. The Casio also offers aspect ratio flexibility including 4:3, 3:2, and 16:9, whereas Canon is limited to 4:3 and 16:9.

While neither camera supports RAW capture, the Canon’s sensor combined with Digic 4 yields more natural color gradations and less need for in-camera sharpening compared to the Casio’s images. However, the Canon’s CCD sensor leads to more noticeable noise at ISO 800 and above.

LCD Screen and Viewfinder Usability - Composing Your Shot

Most photographers will spend many minutes scrutinizing LCD quality and inventorying viewfinder fidelity. Here, the Canon again asserts an advantage:

The Canon SX20 IS boasts a fully articulated 2.5-inch LCD screen with 230K dots, which gives flexibility in composing awkward angles or shooting video selfies - though “selfie-friendly” is a stretch for a 2010 bridge camera.

The Casio has a slightly larger fixed 2.7-inch screen at the same 230K resolution but lacks articulation and any viewfinder whatsoever. The absence of an electronic or optical viewfinder on the Casio EX-FC100 can be a critical limitation under bright sunlight.

The Canon includes a basic electronic viewfinder (EVF), although resolution specs aren’t published and it’s admittedly a low-res EVF. Still, it offers a composition alternative and reduces LCD power drain. The Casio’s lack of any viewfinder means you must rely exclusively on the LCD.

For prolonged outdoor shooting and rapid framing, I found the Canon's articulating screen and EVF combination more practical.

Autofocus and Shooting Performance - Speed vs Simplicity

Autofocus speed and accuracy can make or break shooting moments across genres.

The Canon SX20 IS employs a contrast-detection AF system with 9 focus points and offers multi-area AF. Its ability to stick to a subject during continuous shooting is limited, as continuous AF tracking is unavailable.

The Casio EX-FC100 provides a simpler contrast-detection AF with no dedicated focus points and no face detection or tracking.

Continuous shooting rates reveal one of the SX20’s major drawbacks: its maximum burst rate is an underwhelming 1.0 fps, notably sluggish for capturing action.

The Casio’s continuous shooting specs are unspecified, but real-world tests indicate slow shot-to-shot time. Neither camera provides advanced AF tracking, which limits their usefulness for fast-moving subjects.

Canon’s AF feels more deliberate and accurate at static subjects, while Casio often hunts, resulting in slower acquisition.

Lens and Zoom Capabilities - Versatility in Focal Length

Here, the Canon leaps ahead with a truly impressive zoom range and lens aperture specifications.

The Canon SX20 IS features a 28–560mm equivalent zoom (20x optical zoom) with a bright maximum aperture of f/2.8 at wide and f/5.7 at telephoto. This extensive range lets you capture everything from wide landscapes to distant wildlife without changing lenses.

In contrast, the Casio EX-FC100’s focal length is not explicitly specified. It has a 5.8x crop factor multiplier, but lacks detailed focal range disclosure - suggesting a more modest zoom. Its aperture ranges from f/3.6 to f/8.5, slower than the Canon, limiting low-light and subject isolation capabilities.

For users craving telephoto reach with good aperture speed, the Canon’s lens is a decisive advantage.

Performance across Photography Genres - Practical Insights

Let’s explore how these two cameras hold up in a range of photographic disciplines, combining technical specs with user experience to match each camera to real-world needs.

Portrait Photography

Capturing pleasing skin tones and attractive bokeh requires good color rendering, precise autofocus on eyes, and a bright lens.

• Canon SX20 IS: The Digic 4 processor helps render skin tones naturally, complemented by a wide f/2.8 aperture that enables shallow depth of field at the wide end (limited telephoto bokeh owing to high f-stop). Unfortunately, no face or eye detection AF is present. Manual focus helps in some cases, but autofocus accuracy on eyes at portrait distances is average.

• Casio EX-FC100: Color reproduction is less refined, with CMOS sensor colors occasionally appearing flatter. Aperture at f/3.6 wide limits bokeh, and lack of face detection again hurts focusing precision.

For portrait shooters wanting classic tones and bokeh control, the Canon is the better choice.

Landscape Photography

Landscape photography benefits from high resolution, excellent dynamic range, and weather sealing.

• Canon SX20 IS: While the 12 MP resolution is decent for prints up to A3 size, the small sensor limits dynamic range. No weather sealing restricts rough outdoor use. The bright wide-angle lens (28 mm equivalent) helps for landscapes.

• Casio EX-FC100: The 9 MP CMOS sensor suffers in resolution, impacting large prints. Its slower lens and lack of weather sealing also hinder outdoor usage.

Neither camera excels truly here, but the Canon’s lens and resolution make it preferable for casual landscape work.

Wildlife Photography

Wildlife demands fast and reliable autofocus, long telephoto reach, and decent burst rates.

The Canon’s 20x zoom is a clear advantage for subjects at a distance. Yet, its slow AF and 1 fps continuous shooting drastically limit capturing fast-moving animals.

The Casio has neither the reach nor the AF speed for serious wildlife photography.

Conclusion: The Canon SX20 IS is the only one remotely suitable for basic wildlife, with patience.

Sports Photography

Sports shooting prioritizes frame rates, autofocus tracking, and low light performance.

Neither camera supports continuous AF tracking or burst shooting at competitive speeds. The Canon’s slow 1 fps and Casio’s unspecified, slow shooting performance remove them from consideration for sports.

Street Photography

Discretion, quick AF, and portability are key.

• Canon SX20 IS: Bulky and noticeable, it’s less suited for candid street shots. However, reliable AF and an EVF help capture decisive moments quickly.

• Casio EX-FC100: Ultra-compact and inconspicuous, perfect for street photographers wanting to blend in. AF speed is slower, but for posed or slow candid shots, sufficient.

Depending on priorities, the Casio is the stealthier street shooter.

Macro Photography

Macro photography demands precise manual focus and short minimum focus distances.

The Canon SX20 IS claims a 0 cm macro focus range, allowing close focusing. Manual focus control here is beneficial.

The Casio’s macro specs are unclear; combined with its slower lens, this limits close-up possibilities.

Conclusion: Canon offers better macro ability in practice.

Night & Astro Photography

High ISO performance and long exposure capabilities dictate suitability.

The Canon supports a minimum shutter speed of 15 seconds and ISO to 1600 max. The CCD sensor generates more noise at higher ISOs, but longer exposures remain effective.

The Casio limits max shutter speed to 1 second and ISO max 1600. Its CMOS sensor noise handling is better, but short max shutter speed rules it out for long-exposure astro.

Conclusion: Canon more viable for night photography; Casio better noise at low ISO.

Video Capabilities

The Canon records 720p HD video at 30 fps in H.264 format, with optical image stabilization helping stabilize footage. No external mic port limits audio options.

The Casio also shoots 720p video but uses Motion JPEG format - a less efficient codec - and offers an impressive array of high frame rate slow-motion modes, including a whopping 1000 fps at low resolution.

Neither camera supports 4K or advanced video features, but Casio’s slow-motion modes are a differentiator for experimental video.

Travel Photography

Travel shooters value size, versatility, battery life, and reliability.

The Canon’s size is a downside for packing light, but the impressive 20x zoom reduces lens changes and enables capturing diverse scenes from landscapes to street life.

The Casio’s lightweight compact design is highly portable. Its sensor-shift stabilization compensates somewhat for the slower lens.

Battery life for both is modest; Canon relies on 4x AA batteries, convenient for replacement anywhere. Casio uses a proprietary rechargeable NP-40 battery.

Recommendation: Casual travelers favor the Casio; those wanting flexibility and reach choose Canon.
